“…Moreover, there has been minimal attention to the potential impact of SHS exposure in the early life (i.e., during pregnancy and the first 2 years of life), and we only found two cohort studies (the UK [ 9 ] and the USA [ 10 ]) addressing prenatal SHS exposure and symptom of sleep-breathing in children throughout early childhood. Mechanically, sleep behaviors are regulated by the central nervous system, therefore being sensitive to alterations in brain neurochemistry [ 11 ]. Chemicals in SHS can cross placental barrier during pregnancy and disrupt neurochemistry or influence the development of infants’ brain structure by interfering with the breathing process [ 11 ].…”

Chemicals in SHS can cross placental barrier during pregnancy and disrupt neurochemistry or influence the development of infants’ brain structure by interfering with the breathing process [ 11 ]. However, to our knowledge, no studies include measures of early-life SHS exposure during both pregnancy and the first 2 years of life.…”

Background Previous studies have revealed that current secondhand smoke exposure showed highly suggestive evidence for increased risk of simultaneous sleep problems in children. Data on the associations between early-life exposure to SHS with subsequent sleep problems in children were scarce. We aimed to evaluate the associations of early-life SHS exposure with sleep problems in children. Methods In this cross-sectional study, children were recruited from elementary and middle schools in Liaoning Province, China between April 2012 and January 2013. We assessed early-life SHS exposure (pregnancy and the first 2 years of life) via questionnaires. Sleep problems and different types of sleep-related symptoms were measured based on the validated tool of the Sleep Disturbance Scale for Children (SDSC). Generalized linear mixed models were applied to estimate the associations of early-life SHS exposure with sleep problems. Results We included a total of 45,562 children (22,657 [49.7%] males; mean [SD] age, 11.0 [2.6] years) and 6167 of them (13.5%) were exposed to early-life SHS during both pregnancy and the first 2 years of life. Compared with unexposed counterparts, children exposed to early-life SHS had higher total T-scores of SDSC (β = 4.32; 95%CI: 4.06, 4.58) and higher odds of increased sleep problems (OR = 2.14; 95%CI: 1.89, 2.42). When considering different sleep-related symptoms, the associations between early-life SHS exposure and symptom of sleep-wake transition disorders (i.e., bruxism) were the strongest in all analyses. Conclusions Early-life SHS exposure was associated with higher odds of global sleep problems and different sleep-related symptoms in children aged 6–18 years. Our findings highlight the importance to strengthen efforts to support the critical importance of maintaining a smoke-free environment especially in early life.

“…Brief periods of noise exposure can interfere with work performance [ 58 ] and promote hearing loss that may be irreversible [ 59 ]. Repeated noise exposure or continuous long-term exposure can have non-auditory health consequences; these include sleep disturbance [ 60 ], impaired cognition [ 61 ], circadian dysfunction [ 62 ], vascular dysregulation [ 63 ], and cardiovascular disease [ 64 ]. The severity of such risks has led government agencies to establish standards for occupational noise exposure in numerous countries.…”

Redox Implications of Extreme Task Performance: The Case in Driver Athletes

Redox homeostasis and redox-mediated signaling mechanisms are fundamental elements of human biology. Physiological levels of reactive oxygen species (ROS) and reactive nitrogen species (RNS) modulate a range of functional processes at the cellular, tissue, and systemic levels in healthy humans. Conversely, excess ROS or RNS activity can disrupt function, impairing the performance of daily activities. This article analyzes the impact of redox mechanisms on extreme task performance. Such activities (a) require complex motor skills, (b) are physically demanding, (c) are performed in an extreme environment, (d) require high-level executive function, and (e) pose an imminent risk of injury or death. The current analysis utilizes race car driving as a representative example. The physiological challenges of this extreme task include physical exertion, g loading, vibration, heat exposure, dehydration, noise, mental demands, and emotional factors. Each of these challenges stimulates ROS signaling, RNS signaling, or both, alters redox homeostasis, and exerts pro-oxidant effects at either the tissue or systemic levels. These redox mechanisms appear to promote physiological stress during race car driving and impair the performance of driver athletes.

“…48 The literature suggests that such sound-related arousals or changes could be a consequence of a sympathetic response or follow a modulation in ion channels. 6 They could represent the underlying mechanism of k-complexes, which can be elicited by acoustic stimuli such as tones. 49 Their similarity to slow oscillations (SO), which are supposed to be critically involved in memory consolidation, has provoked researchers to manipulate their occurrence with acoustic stimulation.…”

“…5 Acoustic stimulation is thus used as a means to experimentally manipulate specific sleep features to uncover their contribution to cognition, memory or health factors. Additionally, its impairing effects on sleep, for instance caused by nocturnal environmental noise, are in the scope of research (for an overview see 6 ). Another line of research uses acoustic stimulation before sleep to explore its effects on the upcoming sleep period.…”

With growing interest in the use of acoustic stimuli in sleep research and acoustic interventions used therapeutically for sleep enhancement, there is a need for an overview of the current lines of research. This paper summarizes the various ways to use acoustic input before sleep or stimulation during sleep. It thereby focuses on the respective methodological requirements, advantages, disadvantages, potentials and difficulties of acoustic sleep modulation. It highlights differences in subjective and objective outcome measures, immediate and whole night effects and short versus long term effects. This recognizes the fact that not all outcome parameters are relevant in every research field. The same applies to conclusions drawn from other outcome dimensions, consideration of mediating factors, levels of stimulation processing and the impact of inter-individual differences. In addition to the deliberate influences of acoustic input on sleep, one paragraph describes adverse environmental acoustic influences. Finally, the possibilities for clinical and basic research-related applications are discussed, and emerging opportunities are presented. This overview is not a systematic review but aims to present the current perspective and hence summarizes the most up-todate research results and reviews. This is the first review providing a summary of the broad spectrum of possibilities to acoustically influence sleep.
